If you see a diagonal line across the display screen of your new control board, you'll need to remove the protective film on the screen.
1. Remove the top cover by unhooking the two clips in the back, holding the cover onto the tank below. Be careful to not unplug any wires when removing the cover.
2. Locate the control board on the underside of the cover. Four tabs hold each corner of the board to the lid. Remove the board by unclipping these tabs. Depending on your model, you may have a removable heat sheild covering the board.
3. With the board in your hands, pell the thin protective film off the control board screen.
4. Snap the board back into the top cover and return the cover to the top of the softener.
